I don't at all accept that P:Km traded quality for more options for the player. If anything, I believe the quality of the player's experience increased significantly because of those options
I love P:K and played through it twice. However I definitely think quality or depth of things suffered because of quantity. For example having massive amount of classes, races etc. meant there was zero reactivity to those. I can count the number of times any of those were referred by the game with a single hand. It was also a complete mess for a new comer to try create a character when you have hundred options and very little information what does what.
Or the options, sure there are tons of difficulty options to "tailor" the experience, but I don't want to adjust difficulty sliders in every encounter because balance was all over the place. I want to play the game. Not design and develop it on the fly. It's impossible to try provide a polished experience if there are million permutations of options everybody changes.
